有限元强度折减法在边坡稳定性分析中的有效性及结果检验方法 [PDF]
, 2017 有限元强度折减法的有效性及结果评价决定该方法是否能在工程上得到认可及推广的关键。本文基于有理论解的地基承载力问题和澳大利亚计算机应用协会(ACADS)边坡稳定性典型考题,通过计算值与理论解的对比以及塑性贯通区结果,对有限元强度折减法用于边坡稳定分析的有效性、失稳判据以及结果评价等问题进行了系统研究,提出了以塑性带宽度与长度之比检验计算结果的方法。结果发现,在足够且合理的网格密度下,有限元强度折减法分析边坡稳定性是有效的,不同类型的临界状态判据差异不大,而塑性区贯通判据最为客观 ...

Shuitu Baochi Xuebao, 2017 ：以重庆市城镇建设活动形成的典型工程堆积体为研究对象，对工程堆积体边坡物理力学特性和入渗特征进行了研究，同时确定工程堆积体边坡的危险滑动面及安全系数。在工程堆积体边坡上、中、下设置采样点，采集土壤样品进行土壤物理力学性质分析，采用野外双环入渗法进行入渗过程研究，运用GEO-SLOPE软件分析工程堆积体边坡稳定性。结果表明：（1）工程堆积体粒度分布不均匀，且中坡位>下坡位。（2）工程堆积体饱和含水量随坡位下降呈逐渐增加趋势；入渗率随时间变化呈快速减小、缓慢减小、稳定入渗3个阶段，2 m、2 a和4 ...

Dizhen xuebao运用FLAC3D软件，基于数值模拟计算不收敛、特征点位移突变和塑性区贯通三类经典判据，针对均质土坡模型提出了边坡失稳时彩虹状位移云图的概念，建立了联合塑性区贯通和彩虹状位移云图判别边坡失稳的方法，并与三类传统判据进行了对比计算。结果表明：应用本文所提出的判据得到的安全系数与其它三类判据得到的安全系数相近，且具备操作性强、物理概念明确的优势。其中，采用塑性区贯通为判据得到的安全系数较小，与其它判据得出的结果相差约1.6%，同时证明了本文提出的彩虹状位移云图判据的可靠性和准确性 ...
